These were their orderings in their service to come into the house of Jehovah, according to their manner, to Aaron their father, as Jehovah, the God of Israel had commanded him.
And the Levites and all Judah did according to all things that Jehoiada the priest had commanded. And every man took his men who were to come in on the sabbath, with the ones who were to go out on the sabbath. For Jehoiada the priest did not dismiss the divisions.
Therefore if perfection were by the Levitical priesthood (for under it the people received the Law), what further need was there that another priest should rise after the order of Melchizedek, and not be called after the order of Aaron?
